The CRT board is a third party daughter board. Computron 115DMX. Those bastards filed off the label of the controller IC

There's a floppy drive hidden beneath a flap on the top. I have a policy of checking, cleaning and servicing any and all floppy drives in my machines.
With all the sud that came off the CRT screen, I was expecting a lot more dirt. Basically clean.
It's a Panasonic JU-455-5 double sided double density drive, so 360kB formatted.

The controller board lives directly underneath the drive. It's got a uPD765 floppy drive controller, a
uPD8257 DMA Controller, and a uPB9201 floppy disk interface controller, flanked by 8x8K of static RAM.
Interesting design to have extra RAM on here.
